(5 points) Answer: Since the catalyst used in the methanation reactor is nickel, if the bed temperature is below 150°C, nickel reacts with CO to form highly toxic nickel carbonyl, which poisons and deactivates the catalyst. Additionally, nickel carbonyl is highly toxic and can cause severe harm to the human body. Correct: +5, Explanation: +10, Sharing experience: +20.

Since the methanation reaction is an exothermic reaction, a lower temperature facilitates complete reaction. In actual production, the temperature must take into account both the reaction rate and depth, and be maintained within an appropriate range.
The nickel catalyst used in the methanation reactor forms highly toxic nickel carbonyl with CO at 150°C, simultaneously causing the catalyst to become inactive.
The methanation reaction is an exothermic reaction, and lower temperatures facilitate its progression； At the same time, it prevents the nickel catalyst from deactivating at high temperatures.
The nickel catalyst used in the methanation reactor forms highly toxic nickel carbonyl with CO at 150°C, simultaneously causing the deactivation of the nickel catalyst
Too low a level will result in the formation of nickel carbonyl…………
At too low a temperature, the number of reactively active molecules decreases, which slows down the reaction rate
Reactor penetration is likely to occur! ! ! !

How did you see the answer? This isn’t good, right?
Because my device has a methanation system built in. Used every day!
